3M Filtrete Anti Pollution Filter for converting AC into air purifier (White, 2 Pieces)

I purchased this type of product for the first time. The difference is huge when compared to simple AC filter and the addon AC filter. The dust collected on the 3M filters speaks for itself. I have cleaned it once and still using it. However, I do not recommend cleaning and reuse. Though expensive, during this pandemic, it helps you be safe at home. AC would run for most of the time (nearly 10-15hrs a day) With this much usage, the product really is worth spending for. I have avoided an air purifier because of this.

Installation - Installed within my Hitachi window AC since 2 weeks now. Though designed for a split AC, it fitted my window AC perfectly (refer images) - I did not even have to cut or resize it in any manner (gaps left at both sides for airflow as is recommended). The pack comes with two filters, I have only used onePerformance - Note that I installed it behind my regular AC filter (and not in front of it), meaning that it is catching substances that have passed through the regular AC filter. In only 2 weeks the 3M filter has turned largely black (refer images) - the white lines are where the regular AC filter is shielding the 3M filter and hence where it has retained its original white colour. FYI I live in Kolkata on a relatively quiet dead-end residential street1. The AC output drops slightly - in my case its been small and acceptable. Could however irritate you if your AC is particularly old/weak, or during peak summer months (am currently using it in September in Kolkata)2. For the brutal pollution during winter months in most Indian cities, there is no way this product can match stand alone air purifiers - while its capturing all this 'black', the drop in pollution per my air quality meter is not as fast or strong as an air purifier would be3. My big issue with this product though is its life. On the one hand am happy that it captures all this dirt but on the other hand am unsure how effective it will be after 1-2 weeks once it has turned this blackIn summary, it is definitely not a replacement for air purifiers during winter months. Not very worthwhile for the rest of the year too unless you do not own an air purifier or have packed it away, and install this in your AC so that you get slightly cleaner air at the same time as you are using your AC

Its a good product but dont last more than a month

Does the job, definitely worth buying.Easy to install and use

+18% GST on this product... A recent Lancet report says 25% of all deaths in India are related to air pollution. If you see my last air-filter you would agree. Cannot afford to put a new filter every week.

These filters are made up of very thin material of non woven fibres. In one packet there are 2 filters and 1 packet will serve both net meshes of a wall mounted split AC as you can see in the picture I have attached. Installation of the filters is very simple and leaves no mess. You have to first take out the mesh from your air conditioner. You should then wash it very properly, removing all the lint and fibres from it then you have to install the filters by leaving gap on the sides of both the meshes and then fix the the mesh with the filter in your AC. The filter has double sided tape which can be used to affix it on the margin of the mesh. Further, as a matter of customer friendly gesture, there are 6 small adhesive strips also provided so that no inconvenience is caused in the installation. The air conditioner has started delivering cool and clean air. It should feel very refreshing once you experience it. Overall a good product.

It gets the job done.

I use this product since 1 year I have fitted it on my carrier 1.5 ton split ac and it works perfect , you can feel the purity of air and I get it replaced when the ac indoor unit founds it hard to flow air , and starts flapping, u can hear the sound , it is the time to replace normally I require to replace it in 2 months , but it is cost effective as it fits in my existing ac and I have diverted my mind in not to go for air purifiers which are costly 10k+ and regular costly filter change , u can subscribe and get it more cheaper approx 5rs /day is not cost to worry to breathe easy , excellent product from 3 M
